Question

我正在开发一款Spritekit游戏。

当touchind尝试运行某个操作的节点时，我接收到EXEC_BAD_ACCESS异常

此功能触及

    -(void)selectNodeForTouch:(CGPoint)location {
    SKNode *touchedNode = (SKNode *)[self nodeAtPoint:location];
    NSLog(@"touched : %@",touchedNode.name);

    if([[touchedNode name] isEqualToString:@"piece"]){
        Piece *piece = (Piece *)[self nodeAtPoint:location];
        if ([piece isRotated])
            [piece rotateToFront];
        else
            [piece rotateToBack];
    }
}

对象片段方法rotateBack：

    -(void)rotateToBack{
    SKAction *rotationToBack = [SKAction animateWithTextures:[self animationFrames] timePerFrame:0.11];
    [self runAction:rotationToBack withKey:@"rotation-to-back"];
    [self setRotated:YES];
};

[self animationFrames]是一个NSMutable数组，用

转换为NSArray

[self setAnimationFrames:[NSArray arrayWithArray:frames]];

最后，框架是NSMutableArray，其中包含一些SKTextures

执行在动画执行上有所作为。

在Piece班级

更改此行：

NSString *imageName = [NSString stringWithFormat:@"%@-1%@",[self baseImageName],imageResolution];

到

NSString *imageName = [NSString stringWithFormat:@"%@-1",[self baseImageName]];

SKAction上的EXC_BAD_ACCESS
